There is no way that this is going to work by 2013, what gives the Avengers a glimmer of hope is that the backgrounds to each character will have already been established before the movie, allowing the movie's plot to develop without being entangled in character development. However, seeing that the JLA is going to use a new Batman, Spiderman, and a hoard of other new characters whose backgrounds have not been established, I am rather confident that this film will be two and a half hours of drivel.
